Ideas for planting

My kitchen window faces north and towards my side entrance which is about 1.5m wide. It gets some evening sun. Could anyone suggest some plants to give interest for as much of the year as possible? They would need to grow about 1.5m but not damage my neighbour???s fence or have invasive roots. I have made a simple narrow raise bed to accommodate them.

We've looked at this, and the furthest we can get with uploading images is that the facility will be 'available soon' - also, there aren't the text tools here that are shown on the illustration.

Is it possible that this facility isn't available in all areas?

We've explored the possibility of HTML v Plain Text, but there doesn't seem to be a mechanism for toggling between the two. Hope we're not missing the obvious, but it does seem that quite a number of people are having the same problem.
